    Abstract: The power consumption of a shift register or a display device including the shift register is reduced. A clock signal is supplied to a shift register by a plurality of wirings, not by one wiring. Any one of the plurality of wirings supplies a clock signal in only part of the operation period of the shift register, not during the whole operation period of the shift register. Therefore, the capacity load caused with the supply of clock signals can be reduced, leading to reduction in power consumption of the shift register.

  • Patent number: 11290114
    Abstract: A clock stretcher includes a DLL that derives delayed versions of an input clock signal. The clock stretcher has passive and stretching modes. It operates from a sensed power supply without intervening voltage regulation. In passive mode, it forwards input clock pulses to the clock stretcher output. The input clock pulses are delayed by fewer than 10 DLL delay line delay stages. In stretching mode, a combiner cyclically selects the delayed versions of the input clock signal to generate a modified clock signal. The combiner uses a hop code, dependent on a sensed condition, to determine the step size for the cyclical selection. To enter passive mode, the clock stretcher tests if a passive mode entry threshold is met. The threshold includes two conditions: the hop code must be zero, and phase selection must have reached a wraparound point that may have been corrected for a delay line offset.

  • Patent number: 11290113
    Abstract: A clock stretcher includes a digital DLL that derives delayed versions of an input clock signal, and a combiner that cyclically selects the delayed versions to generate a modified clock signal. The combiner uses a hop code, dependent on a sensed condition, to determine the step size for the cyclical selection. The digital DLL corrects its delay speed at discrete times, during which it may be active. If the DLL delay line becomes slower while it is active, the modified clock signal would incur a glitch. The clock stretcher corrects for this glitch by using an increased hop code when a speed change occurs. The clock stretcher may operate from a sensed power supply without intervening voltage regulation.

  • Patent number: 10838636
    Abstract: The present disclosure describes technologies and techniques for use by a data storage controller—such as a non-volatile memory (NVM) controller—to adaptively and hierarchically scale clock signals distributed to its internal components. In various examples described herein, the data storage controller is configured to downscale the internal clocks of the controller for all processing sub-blocks that are in an Active Idle state (or in similar idle states where a component is active but has no tasks to perform). When an entire hierarchy of components is idle, the clock signal applied to the entire hierarchy is downscaled. By downscaling the clock for an entire hierarchy of components, power consumed by the corresponding clock tree is also reduced. In specific examples, clock signals are downscaled by a factor of thirty-two to reduce power consumption. NVMe examples are provided herein.
